There has always been something a little too perfect about Mitt Romney. He is a lifelong teetotaller, a non-smoker, the kind of fella who eschews salty language for an old-fashioned “aww shucks”, a dedicated family man with an overflowing brood of gorgeous children and grandchildren, and a successful Republican governor in one of the nation’s most liberal bastions, Massachusetts, the home of the notoriously drunken, cursing, womanising and bleeding heart Kennedys.
